For erectile concerns, one of the most important questions is mechanical: how is blood actually moving?
Penile duplex ultrasound is an in-house, physician-performed imaging study that measures arterial inflow and venous outflow in real time. It helps distinguish whether a concern is primarily arterial, venous, or mixed, which can guide which treatments are most appropriate and which are less likely to help.
Without vascular imaging, treatment decisions often rely more heavily on symptoms, history, and response over time. With penile duplex ultrasound, your plan is informed by real-time vascular data and interpreted by your physician as part of the assessment.
In many conventional care pathways, treatment begins with the symptom. FORM Men’s Health begins with the biology underneath it.
Led by fellowship-trained urologist Dr. Noah Stern, the program is built around a diagnostic-first assessment of the vascular, hormonal, metabolic, and neurological factors that can affect sexual function, energy, performance, and long-term health. Because what is driving the issue determines what should happen next.
Erectile function depends on healthy blood flow, which means changes in erectile function can sometimes reflect broader vascular or metabolic health. Treating the symptom alone can miss that signal.
At FORM Men’s Health, we assess how the vascular and hormonal systems are functioning, so a concern that may begin with sexual performance is understood in the context of wider health. That is the difference between simply managing a symptom and understanding what may be driving it.

Care begins with a structured assessment that looks at the full system: vascular health, hormonal balance, metabolic function, sleep, and neurological factors, rather than a single marker or symptom.
From there, treatment is precise, personalized, and medically grounded: designed to restore underlying function and support long-term health, not just suppress symptoms. Where that foundation is already strong, the focus shifts to optimizing performance and longevity.
Together these connect sexual and hormonal health to your broader healthspan.


Erectile function evaluated across vascular, hormonal, neurological, structural, and psychological factors, with treatment built on what the assessment shows.

Testosterone and related pathways are assessed in the context of energy, body composition, mood, cognition, libido, fertility goals, and metabolic health, then managed and monitored carefully over time.

Prostate-related concerns, pelvic discomfort, and changes in flow, urgency, frequency, or nighttime urination are assessed in context, with next steps guided by the clinical picture.

Reproductive goals considered as part of hormone, sexual-health, and treatment planning, especially before any protocol that may affect sperm production.

Specialized assessment and non-surgical and procedural options for structural conditions, with ongoing monitoring for function and comfort.

Weight, metabolic health, energy, sleep, and healthspan-related concerns are considered as part of the broader assessment, with connection into the appropriate FORM resources when clinically relevant.

Focused low-intensity shockwave therapy: Uses acoustic energy to support blood flow and vascular response, targeting arterial inflow over time rather than relying only on short-term symptom management.
Radiofrequency therapy: Controlled thermal energy that may support tissue quality and responsiveness, used as an adjunct where the assessment suggests venous function or tissue factors may be contributing. This is mechanism-specific for erectile concerns, not pelvic-floor or incontinence treatment.
Fertility-first hormone optimization: Personalized, monitored hormone care built on the fertility-first standard above, with fertility goals documented before treatment decisions are made.
Targeted medical therapy: Where clinically appropriate, medication and other medical options are matched to the assessment findings, symptoms, goals, and risk profile.
Coordinated care planning: Where concerns extend beyond sexual or hormonal health, the plan may connect into broader FORM resources for metabolic health, fitness, recovery, nutrition, or long-term optimization when clinically relevant.
Treatment is matched to what your diagnostics show, not applied as a one-size protocol.
This information is educational and does not replace medical advice. Assessment and treatment recommendations vary by patient and are made only after clinical evaluation by an appropriate healthcare professional.
Some patients need a focused assessment and treatment plan. Others benefit from a more ongoing relationship with continued monitoring, reassessment, and access to broader FORM resources when clinically appropriate.
Start with clarity: Your care begins with a comprehensive men’s health assessment designed to understand your symptoms, goals, health history, and key diagnostic findings. From there, Dr. Stern develops a clear view of what may be contributing and what options may be appropriate.
Move into targeted care: When treatment is recommended, your plan is matched to the findings from your assessment. Depending on your needs, this may include medical therapy, device-based therapies, hormone care where appropriate, or coordinated support from other FORM services.
Track progress over time: Men’s health changes with age, stress, fitness, hormones, metabolism, and overall health. Follow-up care allows your plan to be monitored, adjusted, and refined based on how you respond.
For founders, executives, and high-performing individuals who want continuity rather than one-off visits, FORM Men's Health offers a concierge model: ongoing physician oversight, repeat diagnostics, and continuous refinement of your plan, a dedicated medical partnership where health, performance, and longevity are managed through structured oversight, repeat diagnostics, and ongoing refinement. An integrated option, co-delivered with FORM's longevity physician, extends this across metabolic, cognitive, and longevity care under a single coordinated relationship.

Dr. Noah Stern is a Fellowship-Trained Urologist with expertise in men’s sexual health, hormonal optimization, and reconstructive urology. He studied Life Sciences at Queen’s University and completed medical training at Western University. After his urology residency, he specialized in reconstructive urology at the University of Toronto with Dr. Sender Herschorn. Dr. Stern excels in treating erectile dysfunction, hormonal health, penile rehabilitation, and Peyronie’s disease using advanced diagnostics and evidence-based treatments. He holds hospital privileges at North York General Hospital and Mackenzie Health and contributes to global research in sexual medicine through collaboration with Dr. Gerald Brock.
Some urological procedures or diagnostic tests may be covered under specific plans; however, many of our optimization and longevity programs are private. Our team can help you navigate the information based on your specific treatment.
While many men start to wonder about their levels in their 40s or 50s, we see patients of various ages. If you are feeling a decline in energy or sex drive, it is the right time to book an appointment for blood work.
Research shows that erectile dysfunction is often an early sign of heart disease. By improving your diet and exercise, you improve blood flow, which is essential for sexual health and preventing future illnesses.
A urologist is a specialist who has spent years researching and treating the male reproductive and urinary systems. At FORM, our experts provide a higher level of specialized care than a general practice.
